The Poisson’s Ratio of enamel, dentin and dental restoration materials
Эндодонтия Today, 2019 The Poisson ratio and the Young’s modulus form a pair of independent material constants of solids. For hard tooth tissues the Poisson’s ratio should correspond to the Poisson’s ratio of restorative materials in order to avoid overstresses at the border ...

Poisson's ratio in composite elastic media with rigid rods [PDF]
, 2010 We study the elastic response of composites of rods embedded in elastic media. We calculate the micro-mechanical response functions, and bulk elastic constants as functions of rod density.

Poisson's ratio and Young's modulus of lipid bilayers in different phases
Frontiers in Bioengineering and Biotechnology, 2014 A general computational method is introduced to estimate the Poisson's ratio for membranes with small thickness.In this method, the Poisson's ratio is calculated by utilizing a rescaling of inter-particle distancesin one lateral direction under periodic ...

On three-dimensional dilational elastic metamaterials [PDF]
, 2013 Dilational materials are stable three-dimensional isotropic auxetics with an ultimate Poisson's ratio of -1. We design, evaluate, fabricate, and characterize crystalline metamaterials approaching this ideal.

Poisson's ratio in cubic materials
, 2006 Expressions are given for the maximum and minimum values of Poisson's ratio $\nu$ for materials with cubic symmetry. Values less than -1 occur if and only if the maximum shear modulus is associated with the cube axis and is at least 25 times the value of

A class of auxetic three-dimensional lattices
, 2015 We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed in order to have omni-directional Poisson's ratio arbitrarily close to the stability limit -1.
